Post-stroke dizziness and vomiting are clinically common in posterior circulation strokes, mainly due to neurological deficits after brainstem and cerebellar ischemia, manifesting as dizziness, visual rotation, nausea, vomiting, and also numbness and weakness of the limbs and walking obliquely. Some patients may also have cerebellar chanting-like language, which can be diagnosed by CT or MRI of the head. In the case of anterior circulation cerebral infarction, the patient is considered to have a large infarct area with cerebral edema. Since the patient with cerebral edema may have dizziness, headache, nausea, vomiting, and also jet-like vomiting, the patient may be given a CT or MRI of the head. Treatment of stroke should be accompanied by dehydration and cranial pressure lowering drugs such as mannitol or glycerol fructose. The patient’s vital signs should also be monitored to avoid brain herniation.
